ROUTE A
Drive: Take Highway 108 to Sonora Pass Trailhead, which is 0.2
mile west from the sign marking Sonora Pass. There is plenty of
paved parking, but no camping is allowed.
Climb: Take the trail to the right of the restroom and past a
sign "Carson-Iceberg Wilderness." This trail is also
marked "PCT." After small ups-and-downs traversing several
gullies, the trail takes a long switchback right to a small saddle.
A 10 foot high, rocky bump sits here, to the right (south). From
here, a steep use trail leaves the PCT going left (north) and
up, just past a thicket of scrubby pines. Staying slightly to
the left of the ridge, pass some crags, following a pronounced
use trail. Nearing the summit past all the crags, follow the class
1 east ridgeline, or use trail, to the highpoint.
As an alternate, the top can be reached from the other side (see
Stanislaus Peak, Route A, Climb), hiking up from St. Mary's Pass.
This route has a somewhat gentler gradient.

Notes: Sonora Peak is the
highest point of Alpine County, and is one of the easiest, higher
elevation peaks to climb. The trailhead is 9,690 feet elevation.
The great view makes this a good introductory peak for the High
Sierra to the south.
